These Aluminum Generator Boxes are designed and built for housing an electric power generator. They can be mounted on the side of a semi truck frame, on top of a truck frame, behind a sleeper or day cab, or in front of the 5th wheel hitch of a pickup truck or any kind of utility or construction site equipment.

Its side accessible door allows the operator to have easy access to the generator controls without having to open the main lid of the box. Air intake and exhaust grills let you operate your generator with closed locked doors to prevent theft, overheating and road grime from ruining your high priced investment. Front access door, intake and exhaust grills can be configured to fit your requirements. We can also add, per your specifications, a box divider to give a little of that always needed cargo space.

Generator Box Features: An engineered aluminum .125 smooth/.100 tread construction; fully seam welded on all seams and corners; stainless steel continuous hinge on full length of lid/door; gas springs to "pop" and keep lid open; channel braced reinforced lid; lockable stainless steel latch; adjustable lock striker for positive weather seal; durable steel intake and exhaust grill; front access panel for convenient access. automotive style latch with smooth rotary action. Mounting kit not included (M3200D).
